Specification of Letters Patent.

Fatented N ov. 9, 1920.

Application filed December 9, 1918. Serial No. 265,915.

To all 10 tem t may concern.'

Be it known that I, CLARK NOBLE lVIsNEn, a citizen ofthe United States,' and a resi dent of New Orleans, in the parish of Orleans and'State of Louisiana, have invented certain new and useful Improvements in .Flying-lvlachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableother's skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in iiying machines and more particularly to ae1'oplanes,one object of the invention being to so construct an aeroplane that it shall be stable at all times; so that it will not descend too rapidly; and so that it shall be strong and simple in construction.

With this and other objects in View, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure l is a View in elevation of a iying machine embodying my improvements, and Fig. 2 is an end View, with the rudders omitted.

l, 2, 3 represent a plurality ,of wings or planes (three such wings or planes being shown in the drawings) made elongated in form and extending substantially the full length of the machine.

These planes are so disposed that they will be parallel with the longitudinal center of the machine and so that each plane shall be .disposed at right angles to shafts 4, 5 located in the center of the machine'. The inner edges of the planes are connected with hubs 6, 7 through which the shafts 4-5 pass, by means of spokes 8, and the outer portions of the several planes are connected by brace rods 9-l0. These braces form4 a frame and so connect the planes that strain on each of the planes shall be transmitted to the others, thus holding the several planes in one rigid structure.

The shaft lis made rigid with the hubs 6 and constitutes part of the framework and this shaft may assist in supporting a suitable passenger' car (not shown).

The shaft 5 is revolubly mounted in the hubs 7 and carries a plurality of propellers ll, 12, 13, each having outwardly and forwardly projecting blades. The shaft 5 may be made in two sections 5 and 5b connected by a clutch 14 and separate engines 15-l6 may be connected with the respective shaft sections.

Suitable rudders 17 may be located at the rear ends of the several planes.

Various changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is

l. An aeroplane, comprising a plurality of planes each disposed at right angles to the axis of the machine and at an angle to each other and extending approximately from end to end of the machine, central supporting means for the planes, said supporting means including two shaft sections coincident with the axis of the machine, a propeller carried by each shaft section, means for connecting said shaft sections, and separate means for driving each shaft section.

2. An aeroplane comprising a central fixed shaft, a propeller shaft in line with the fixed shaft, hubs for said shafts, propcllcrs on said propeller shaft, means for driving said propeller shaft, a plurality of vplanes each disposed at right angles to the axis ofthe machine, said planes having their longitudinal axes parallel with the axis of thc machine and extending approximately from end to end of the latter, spokes connecting the inner edges of said planes with the hubs Ythrough which the central shafts pass, and braces connecting the outer portions of the several planes.

In testimony whereof, I have signed this specification in the presence of two sulscribing witnesses.

CLARK NOBLE IVISNER.
